Biochar is known as a huge carbon storage in the soil. In the soil, biochar absorbs CO2 from air and keep them for hundred years. In addition to preventing reduce emission and green house effects, Biochar also contributes to soil productivity such as physical dan chemical properties of the soil. How biochar amends soil physical properties combined with some tillage systems are imperative to find out. Study aimed to determine the influence of biochar and tillage systems on some soil physical properties. Treatment arranged in a factorial randomized block design with three replications. The treatment of biochar effect consisting of four levels; 0, 10, 15, and 20 t ha-1 Biochar. The tillage systems were three levels; no, minimum, and conventional tillage. The results showed that we found an interaction effect on the biochar application with tillage systems on dried bulk density, soil porosity, and soil permeability. No interaction was found on aggregate stability indexes and soil water holding capacity at water content at -0.3 and -15 bar of water potential (pF 2.54 and 4.2, accordingly). Biochar amounting 10 t ha-1 combined with minimum tillage gave significant benefits on soil productivity in terms of dried bulk density, porosity and soil permeability.

Abstrak. Indeks stabilitas agregat tanah merupakan merupakan ukuran dari kemampuan agregat tanah dalam bertahan terhadap gaya yang merusak agregat tersebut. Lereng dan penggunaan lahan dapat memberikan pengaruh yang berbeda terhadap stabilitas agregat tanah. Semakin curam keadaan suatu lahan maka resiko bahan organik tererosi juga semakin besar, dimana bahan organik memiliki fungsi sebagai salah satu pengikat antar agregat tanah. Tutupan lahan yang baik dapat melindungi tanah dari tumbukan butir hujan sehingga dapat melindungi agregat tanah agar tidak mudah rusak, selain itu vegetasi pada suatu lahan dapat menyumbang bahan organik. Penelitian ini mengkaji bagaimana lereng dan penggunaan lahan dapat mempengaruhi indeks stabilitas agregat tanah. Penelitian ini dilaksanakan di Kecamatan Bukit Kabupaten Bener Meriah pada lereng 0 - 8%, 8 - 15%, 15 - 25 % pada penggunaan lahan kebun kopi dan kebun campuran. Penelitian ini mengamati empat parameter yaitu kemantapan agregat dan faktor pendukung berupa C-organik, tekstur dan struktur tanah. Hasil penelitian menunjukkan bahwa kebun campuran cenderung memiliki indeks stabilitas agregat tanah yang lebih tinggi meskipun masih dalam satu kriteria yang sama yaitu agak stabil. Indeks stabilitas agregat tanah tertinggi terdapat pada SPL 6 sedangkan indeks stabilitas agregat tanah terendah terdapat pada SPL 2.The analysis of The Stability of Soil Aggregates on Some Classes of Slope and Land Use in the District of Bukit Regency Bener MeriahAbstract. The aggregate stability of the soil is a measure of the ability of soil aggregates in enduring style that spoil the aggregate. The slope and land use can provide different influences on the stability of soil aggregates. The more steep the state of a land then the risk of organic matter eroded is also greater, where the organic material has a function as one of the fastener between soil aggregates. Land cover can better protect the ground from the collision of grains of rain so it can protect the soil aggregates that are not easily damaged, in addition the vegetation on the land can be accounted for organic materials. Penany years of research examines how the slopes and land use can affect the stability of soil aggregates. This research was conducted in the District of Bukit Regency Bener Meriah on the slopes 0 - 8%, 8 - 15%, 15 - 25 % on land use coffee plantation and gardens mixture. This study observed the four parameters namely aggregate stability and supporting factors in the form of C-organic, soil texture and structure. The results showed that the mixed gardens tend to have an index of aggregate stability of the soil is high, although still in the same criteria that is somewhat stable. The aggregate stability of the soil was highest in the SPL 6 (land unit) while the stability of soil aggregates lowest SPL 2 (land unit).

Abstrak. Tanah dan lahan seringkali dianggap sama, padahal kedua istilah tersebut memiliki makna yang berbeda. Tanah merupakan kumpulan dari benda alam di permukaan bumi yang tersusun dalam horizon-horizon, terdiri dari bahan campuran mineral, bahan organik, air dan udara, dan merupakan media untuk tumbuhnya tanaman. Tanah dianggap sebagai tubuh alam yang berdimensi (dalam dan luas) merupakan hasil kerja gaya pembangun dan penghancur dan merupakan tempat bagi tanaman. Sedangkan Lahan adalah permukaan bumi yang berupa tanah, batuan, mineral dan kandungan cairan yang terkandung didalamnya yang memiliki fungsi tersendiri yang dapat dimanfaatkan manusia, Blang jeurango merupakan salah satu kecamatan yang terletak di Kabupaten Gayo Lues dengan berbagai jenis tanaman budidaya, berupa tanaman pangan dan tanaman perkebunan. Dari berbagai penggunaan lahan, lahan tersebut memiliki kemampuan laju infiltrasi yang berbeda-beda yang pada gilirannya akan berpengaruh terhadap penyimpanan air dan ketersediaan air di dalam tanah. Kecamatan Blang jeurango rentan dengan terjadinya banjir karena laju infiltrasi daerah tersebut lebih kecil dari intensitas hujan. Besarnya banjir yang terjadi tergantung pada perbandingan kemampuan infiltrasi dan intensitas hujan. Metode yang digunakan pada penelitian ini adalah metode survei deskriptif, yaitu dengan melakukan observasi di lapangan dengan pengukuran laju infiltrasi dilakukan dengan menggunakan double ring infiltrometer. Pengamatan juga dilakukan terhadap beberapa parameter adalah: permeabilitas, bulk density, tekstur tanah, C-organik tanah, porositas, dan laju infiltrasi. Objek penelitian adalah Desa Blang Jerango di Kabupaten Gayo Lues. Nilai laju infiltrasi di Kecamatan Blang Jeurango memiliki klasifikasi laju infiltrasi agak cepat, sedang, dan agak lambat. Agak cepat (6,60 – 7,80 ) terdapat pada SPL 1,2, dan SPL 5, dan kriteria sedang (3,00 – 6,00 ) terdapat pada SPL 4, dan SPL 6, sedangkan agak lambat (0,60 – 1,80 terdapat pada SPL 3 dan SPL 7Kata kunci: Laju infiltrasi, penggunaan lahan, jenis tanahStudy Of Infiltration Rate On Various Land Use And Soil Types In Blang Jeurango DistrictAbstract. Land and land are often considered the same, even though the two terms have different meanings. Soil is a collection of natural objects on the earth's surface arranged in horizons, consisting of a mixture of minerals, organic matter, water and air, and is a medium for plant growth. Soil is considered as a natural body whose dimensions (deep and wide) are the result of the work of building and destroying forces and are a place for plants. While land is the surface of the earth in the form of soil, rocks, minerals and the liquid content contained therein which has its own function that can be utilized by humans, Blang jeurango is one of the sub-districts located in Gayo Lues Regency with various types of cultivated plants, in the form of food crops and plants. plantation. From various land uses, these lands have different infiltration rate capabilities which in turn will affect water storage and water availability in the soil. Blang Jeurango District is prone to flooding because the infiltration rate of the area is smaller than the intensity of the rain. The amount of flooding that occurs depends on the ratio of the infiltration capacity and the intensity of the rain. The method used in this study is a descriptive survey method, namely by making observations in the field by measuring the infiltration rate using a double ring infiltrometer. Observations were also made on several parameters, namely: permeability, bulk density, soil texture, C-organic soil, porosity, and infiltration rate. The object of research is Blang Jerango Village in Gayo Lues Regency. The value of the infiltration rate in Blang Jeurango Subdistrict has a classification of rather fast, medium, and rather slow infiltration rates. Slightly fast (6.60 – 7.80 ) is found in SPL 1,2, and SPL 5, and moderate criteria (3.00 – 6.00 ) found in SPL 4, and SPL 6, while a bit slower (0.60 – 1.80 ) was found in SPL 3 and SPL 7.Keywords: Infiltration rate, land use, soil type

Abstrak. Gambut terbentuk dari tumpukkan sisa tumbuhan yang sudah mati, baik sudah melapuk maupun belum. Tumpukkan akan terus meningkat karena proses dekomposisi terhambat oleh keadaan anaerob serta keadaan lingkungan lainnya yang mengakibatkan rendahnya tingkat perkembangan biota pengurai. Tingkat kematangan gambut sangat menentukan tingkat produktivitas lahan gambut, karena sangat berpengaruh terhadap tingkat kesuburan tanah gambut dan ketersediaan hara. Selain kematangan, kedalaman gambut merupakan faktor penentu untuk dapat tidaknya suatu gambut dijadikan lahan pertanian dan perkebunan serta menjadi salah satu pertimbangan dalam pengelolaan lahan gambut untuk pengembangan pertanian. Penelitian ini dilakukan di PT. Nafasindo dengan menggunakan metode survei deskriptif melalui survei lapangan dan pengamatan lapangan. Pengambilan sampel di lapangan berdasarkan perbedaan tahun tanam yaitu tahun 2004, 2006, 2008, 2010 dan 2013 pada setiap tahun tanam diambil tiga sampel tanah. Hasil penelitian menunjukkan terdapat dua tingkat kematangan gambut yaitu tingkat hemik dan saprik. Lahan yang ditanami gambut tahun 2008, 2010, dan 2013 tergolong dalam tingkat kematangan hemik dan lahan yang ditanami tahun 2004 dam 2006 tergolong ke dalam tingkat kematangan saprik. Kedalaman gambut di PT. Nafasindo tergolong dalam tingkat kedalaman sedang dan dalam. Lahan yang ditanam pada tahun 2004, 2006, 2008 dan 2013 tergolong dalam kedalaman sedang dengan kisaran kedalaman 103,00 ± 7,94 cm sampai 133,33 ± 4,62 cm, sedangkan lahan yang ditanami pada tahun 2010 tergolong ke tingkat kedalaman dalam dengan kedalaman 280,00 ± 0,00 cmMaturity Level and Depth of Peatland Converted to Oil Palm Plantations at PT. Nafasindo Aceh Singkil RegencyAbstract. Peat soil is formed from piles of dead plant residues, whether decomposed or not. The pile will continue to increase because the decomposition process is hampered by anaerobic conditions and other environmental conditions, which result in a low level of development of decomposing biota. The level of peat maturity greatly determines peatlands productivity because it greatly affects the level of peat soil fertility and nutrient availability. In addition to maturity, peat thickness is a determining factor for whether or not peat can be used as agricultural land and plantations and is one of the considerations in peatland management for agricultural development. This research was conducted at PT. Nafasindo uses a descriptive survey method through field surveys and field observations. Sampling in the field based on differences in planting years, namely 2004, 2006, 2008, 2010, and 2013, three soil samples were collected in each planting year. The results showed two levels of peat maturity, namely the hemic and sapric. Land planted in 2008, 2010 and 2013 was classified as hemic maturity level, and land planted in 2004 and 2006 was classified as sapric maturity level. Peat thickness at PT. Nafasindo classifiedas medium and deep thickness levels. The land planted in 2004, 2006, 2008, and 2013 was classified as medium thickness with a depth range of 103.00 ± 7.94 cm to 133.33 ± 4.62 cm, while the land planted in 2010 was classified as deep thickness with depth 280.00 ± 0.00 cm.
